ARTIFICIAL VENEER.

In wood. graining or marbleizing as ordinarily practiced, considerable time and highly skilled labor are essential, but in. carrying out the present process the graihing or marbleized effect is first made on a flexible sheet, and is transferred directly to' the surface to which it is to be applied, the transfer work being quicklyaccomplished at trifling expense, while in the preparation of the veneer or transfer, machinery may be employed, so that the work be of uniform quality and may be produced at very small cost.

In the accompanying drawingsz Figure l is a perspective view showing a prepared board and a roller thereon for removing the filler applied to said board and transferring the grain design from the board to the roller; Fig. 2 is a cross section of a board showing the grain thereof and the filler applied thereto, 011 a greatly-exaggeratedscale; Fig. 3'is across section of the roller shown in Fig. 1 with the filler received'from the board, and of another roller to which this filler is tobe transferred, in operative relation to the firstnamed rollergi Fig. 4 is a cross section ofa machine for transferring a design in ink from the prepared roller to the prepared sheet, the view being partially diagrammatic; Fig. '5- is an enlarged "view showingthe manner of applying the design to the partially finished veneeryand 6 is an exaggerated section of a por-- tion of the veneenready to be applied to a board.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figuresof the drawings.

In making the veneer, a flexible foundation 10 is, employed, the foundation being preferably in the form of a sheet of paper. This fdundatiou is coated\ on one face withalayer 11 on which the veneer is built up, and this layer which forms .a connection between the veneer proper and the foundation, is made of mate-,

rial which will permit the ready separation of the paper after the latter has been softened by moisture. The layer 11 is preferably formed of a .mixture of one half glue and one half carrageen, (Chondrus mlspus).

After this layer, which may be called-the'releaser, has

. dried, thefe is applied to this releasei' a coat of elas varnish, and the latter is allowedto dry over period of. twenty-four hours, more or less. on this coat of elastic varnish an imitation of wood grain or marble is produced, and over this a coat-of paint isapplied, the

latter serving the same purpose as the ground-coat for coat of paint aslow drying oil is used to prevent the veneer from becoming brittle: Finally an add t onal coat, consisting of a solution of pipe clay and sugar of lead, is added. This latter layer serves two purposes, namely,.the pipe clay prevents the surface of the artificial veneer from adhering to any of thesurfaces permit of the rolling of the veneer in order that ,the' same may be conveniently carriedandv handled. The sugar of lead will promote the drying of the veneer :after it has been applied to any surface.

this artificial veneer, the surface-to be treatedis given a coat of varnish paint of a very adhesive nature. The latter is allowed to dry until it has a strong sticky surface. The artificial veneer is then placed over this the air bubbles between the veneer and surface. The paper then thoroughly saturated with warm water sheets, t he sheets may be provided with small perforationsjio permit the more ready escape of the air.

effect by machinery, provision is made for seeming a transfer from natural surfaces. To imitate oak grain- Tug or wood of'any coarse grain, a board of the desired character is first planed and sandpapered, and then is dried, the surface is gone over with a leather or rubber scraper. Over this surface is then passed a roller made of glue, glycefin'and molasses or other suitable material,'a.nd injpassing this roller over the board, the filler projecting portion of the grain which has been cleaned by the scraper, is taken up by the roller. This imitation is now transferred from the soft roller to a roller 20 that is made of close-grained wood,- such forinstance so constructed that the outside of the roller is of end ,wood, so that the roller cannot shrink more on one side I than on the other, or become distorted. This roller is painted a light color, and is b'rought into contact with the soft impression roller, the two rollers being rotated .and the filler being transferred from the soft roller to the light surface of thewooden roller. Having thus prepared the wooden roller, all of .the surface of the latter that is coated by the transferred filleiis cut away,

wood, will present sharp and durable edges;- The par per having been prepared by the application of the releasing layer, and the coat ofvarnish 11, may'be furstance as raw sienna or when The wooden a roller 23 that is-provided with a covering oh'ubberot with which it may come into contact, so that it surface and carefully rolled imo'rder todrive out.

When this filler has partly which remains in, the surface and slightly below the as hard maple, gum' or beech. This wooden-roller is leaving the grainalone toipr'ojectiand this being end ther' provided with a transparent coat, such for in- I i .110 roller is then mounted'in a frame 21 at a point above v other yieldable material and above the wooden roller is arranged an inking roller 25 which may be formed-of any suitable material that will carry the ink. This roller by coming into contact with the engraved roller will ink the latter and when the prepared paper is placed between the lower roller and the engraved roller, and the rollers are turned, an imitation will be transferred from the engraved roller to the varnish coat onthe paper. "After this coating is dried, a coat of paint is added, such, for instance, as a painter would apply to a surface as a ground work'ior gr'aining, and after this the pipe clay and sugar of lead are added.

When an imitation of close grain wood is desired or an imitation of marble or other stone is to be made, the surfaceis treated with "a destructive acid,which will eat away the softer parts, after which the filler is applied and-the suriacenubbed or cleaned to leave the grain exposed. The transfer is then made to the soft roller in the manner previously described. The artificial veneer which formsthe subject of the present in ention may be applied to any surface and used for either outside or inside work, or for the finishing of articles of furniture. The graining being transferred from natural surfaces, is more attractive and uniform than it is possible for the most expert workman to accomplish by hand, while the cost of application is but a small fraction of the expense now incurred in graini ng or marbleizing, I claim:-

1. An artificial transfer veneer'comprlsing an absorbent base of yleldableorflexible .material, a releasing layer thereon, an ornamental varnish layer on the releasing layer, a layer of paint on the varnish layer, and a final layer of non-fibrous, non-adheslve -material on the layer of paint.

3. An artificial veneer comprising a base of flexible material, a releasing layer thereon, a pluralityot layers of paint or the like on the releaslng layer, and a non-adhesive layer formed of pipe clay and suganof lead arranged on top of the layer of paint.

4. An artificial veneer comprlsing a flexible absorbent base,.a releasing layer thereon, an ornamented layer of varnish or the like on the releasing layer, a layer of slowdrying paint on the ornamented layer ,of varnish, and a non-fibrous, non;adhesive layer on thelayer of paint.
